In accordance with Arizona Administrative Code (AAC) R18-5-502 through -509, PDEQ is authorized to review and approve plans for water line extensions,
modifications, or relocations, as well as new water sources,
tanks, or other infrastructure for a Public Water System, in
order to ensure that it is constructed in accordance to State
standards and engineering guidelines published by the Arizona Department of Environmental Quality (ADEQ) under Engineering Bulletin Number
8 and Number 10.
Prior to beginning construction, an Application for Approval To Construct must be submitted to PDEQ, along with the relevant documents outlined in the Plan Review Submittal Checklist. PDEQ will review the submittals, following the Engineer's Plan Review Checklist and, if appropriate, issue an Authorization to Construct (ATC).
After the Authorization to Construct (ATC) is obtained, the facility may be constructed.
After construction, but prior to use, the applicant shall submit verification documents to the appropriate agency. If it is a City Of Tucson or any
Water Improvement District project, they will submit the information
to ADEQ. If the project is for any other Public Water System, the applicant shall submit "As-built" plans, an Engineers Certificate of Completion, and results of pressure, chlorination, and microbiological testing (example form) to PDEQ. Upon review, and if acceptable, PDEQ will issue an Approval Of Construction (AOC) .
After the Approval Of Construction (AOC) is obtained, the facility
may be operated.
